Less busywork. Better documents.

Nebula Writer is the AI agent for your documents. It edits your real files, and you decide what stays.

Most document work isn’t writing.

It’s updating a slide with the final numbers, fixing a total, renumbering tables after a late insert. Chat assistants hand you text to paste back in. Editing the file often means paying for Office or Overleaf.

So we built Nebula to do that work inside the file, show you every change, and keep the editor free forever.

How we build it.

  • Your files, your folder.

    Projects are ordinary folders on your computer. Nothing is locked in.

  • Edit the real thing.

    Nebula changes the Word, PowerPoint, Excel or LaTeX file itself. No copy-paste.

  • You have the final say.

    Every change waits for you. Discard puts the file back exactly as it was.

  • Free where it counts.

    The editor costs nothing, forever. You pay only for more AI.

Who it’s for.

  • Operators and analysts

    Budgets, decks and reports that need the final numbers, today.

  • Researchers and students

    Theses, papers and long LaTeX documents, without an Overleaf plan.

  • Writers and editors

    Drafts and review passes, without losing your voice.
